Question

If cot theta= 1/3, find the value of 1-cos square theta/ 2- sin square theta

Answer 1

Answer:

Step-by-step explanation:

cotФ= $\frac{1}{\sqrt{3} }$

cotФ = 60°                           [∵cot60°= $\frac{1}{\sqrt{3} }$]

we have been given:

$\frac{1-cos^{2} }{2-sin^{2} }$

$\frac{1-\frac{1}{4} }{1-\frac{3}{4} }$

= $\frac{\frac{3}{4} }{\frac{1}{4} }$

= 1  Ans.
